Photovoltaic inverter parameter manual

What is a PV inverter manual?

The inverter is grid-connected, transformer-less, robust and of high conversion efficiency. This manual contains information about the inverter, which will provide guidelines on connecting the inverter into the PV power system and how to operate the inverter. The manual cannot include all information about the PV system.

What is the Aurora photovoltaic inverter installation and operator's manual?

Installation and Operator’s Manual Page 10 of 108 (PVI-3.0/3.6/4.2-OUTD-x-US Rev: 2.1) FOREWORD This document contains a technical description of the Aurora Photovoltaic Inverter which provides the installer and user with the information required for its installation, operation, and use.

How do I install a PV inverter?

Please read the user manual prior to inverter site selection and installation. Connect the RS485 cable to the communication port. Switch the grid supply main Switch (AC) ON first. Switch the DC switch ON. If the voltages of PV arrays are higher than start up voltage, the inverter will turn on. The red LED power will be continuously lit.

How does a PV inverter work?

Display the PV power generation power, feed-in power, etc. The line with an arrow indicates energy flow between connected devices, and the arrow pointing indicates energy flow direction. After being energized, inverter tracks the PV arrays’ maximum power point (MPP) and converts the DC power into AC power. This is the normal operation mode.

What is the main circuit of a PV inverter?

Fig. 2-5 shows the main circuit of the inverter. The MPPT is utilized for DC input to ensure the maximum power from the PV array at different PV input conditions. The inversion circuit converts the DC power into AC power and feeds the AC power to the utility grid through the AC terminal.

Can inverter be connected to PV modules?

Inverter CANNOT be connected to the PV modules, the positive or negative terminal of which needs to be grounded. Any other or additional usage is not permitted except the intended usage. Inverter may only accept PV modules with Protection Class II as its input. Inverter may only be connected to utility grid via distribution board.
